Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2024The c.437C>T (p.A146V) alteration is located in exon 3 (coding exon 2) of the FAM222A gene. This alteration results from a C to T substitution at nucleotide position 437, causing the alanine (A) at amino acid position 146 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
